The American cockroach, Periplaneta americana, has been used extensively in recent years to study aspects of the complex vertebrate nervous system as a simple and accessible invertebrate model. This experiment examined the effects of caffeine on short-term spatial learning in cockroaches using a modified Barnes maze. Prior to every trial, the treatment group was injected with a caffeine solution and the control group was injected with a saline solution. The amount of time required for the cockroach to complete the maze during the initial learning trial was recorded. One hour later, the amount of time required for the subjects to complete a second memory trial was also recorded. A one-tailed t-test between the individual trial times for the control group established that learning had occurred. A two-tailed t¬-test between the individual trial times for the treatment group showed no significant difference. A t-test of means compared the difference in maze completion times between the groups and proved there was a significant difference. Therefore, caffeine did not positively affect short-term spatial learning in cockroaches.

The goal of the experiment was to compare the effect of four different forms of selenium (Se) &minus; sodium selenite (SS), lactate-protein selenium complex (SL), selenium enriched yeast (SY), and selenium-proteinate (SP) supplemented to pregnant goats on Se concentration and glutathione peroxidase (GSH-Px) activity in the blood of goats on the day of delivery and also on Se concentration and GSH-Px activity in the blood of newborn kids. The experiment involved 33 pregnant goats of White Short-haired breed. The supplementation started 6 weeks before the parturition. The goats were divided into 5 groups: control group&nbsp;C, not supplemented, and 4 trial groups (SL, SP, SS, SY), which received Se in the above stated forms by the means of supplemented pellets (300 g per animal per day) at a rate 900 &mu;g Se/kg of dry matter. The average Se concentrations in the blood of the goats were 79.6 &mu;g/l in group C, 152.6 &mu;g/l in group SL, 167.1&nbsp;&mu;g/l in group SP, 144.9 &mu;g/l in group SS, and 152.9 &mu;g/l in group SY. Selenium concentrations in all 4 trial groups were significantly higher (P &lt; 0.01) than in control group, however no significant difference was found between individual trial groups. Likewise, the activity of GSH-Px in goat blood increased significantly in all supplemented groups compared to the controls; however we did not discover any significant differences in activity of GSH-Px between the individual selenium-supplemented groups. The Se concentrations in the blood of kids were significantly (P &lt; 0.01) higher in the selenium-supplemented groups (SL &ndash; 94.9&nbsp;&mu;g/l, <br />SP &ndash; 87.5 &mu;g/l, SS &ndash; 87.6 &mu;g/l, SY &ndash; 92.5 &mu;g/l) than in the control group (C &ndash; 49.4 &mu;g/l), but we did not discover any differences between the individual experimental groups. The activity of GSH-Px in the blood of the kids tended towards higher values in the supplemented groups than in the control group, but the values were significantly higher (P &lt; 0.05) only in groups SY and SL. We have found significant correlation between GSH-Px activity and Se concentration in the blood of goats (r = 0.86) and newborn kids (r = 0.95). Likewise, there was significant correlation between Se concentration in the blood of goats and their kids (r&nbsp;= 0.74). We discovered that the kids are reaching physiologically only about 60% of Se status in whole blood in comparison with their mothers. Our results are suggesting that all the above forms of Se were similarly utilised and transferred into the foetus in the goats. &nbsp;

Background:Sacral fractures are a source of pain leading to loss of autonomy in elderly patients. Sacroplasty may be an effective alternative of conservative medical treatment.Objectives:To evaluate the short-term analgesic effect of sacroplasty compared to conservative treatment in patients with osteoporotic sacral fracturesMethods:This is a retrospective study of cases of osteoporotic sacral fractures treated with sacroplasty, compared with cases treated with conservative medical procedure over the same period. Outcome was evaluated by pain (Visual analogic scale) short-term (one month) evolution and side effects occurrence.Results:From January 2009 to June 2019, eleven patients were treated with sacroplasty for osteoporotic fractures at the Besançon University Hospital Centre. These were compared to 12 patients with osteoporotic sacral fracture with exclusive medical management, as a control group. The two groups were similar in age, gender and pain level at baseline. The median VAS was 7/10 in both groups at baseline, In the sacroplasty group, a significant decrease of pain was observed over the two first weeks, with a tendency remaining at day 30. There were no significant differences in the conservative treatment group at one week (p=0.2), fourteen days (p=0.6) and thirty days (p=0.7) compared to basal assessment.When comparing the sacroplasty group and the conservative treatment group, no differences were noted at baseline between the two groups, there was a significant difference between the two groups the following day (p=0.001), one week (p=0.003) and day 15 (p=0.01) after the intervention. However, there was no significant difference between the two groups at day 30, but only a trend (p=0.08).Regarding analgesic treatments, 30% of patients in the sacroplasty group could reduce their analgesics between the time they entered and left hospital. None of the patients in the control group were able to reduce their analgesic treatment over this period. In addition, half of the patients in the sacroplasty group were successful in returning home compared to only one-third of the patients in the conservative treatment group.Conclusion:In this study, sacroplasty was associated with an early and significant pain relief compared to conservative management in patients with osteoporotic sacral fracture. The procedure is well tolerated and may prevent loss of autonomy in these patients.Disclosure of Interests:None declared

BACKGROUND: Chronic kidney disease (CKD) is a chronic illness with complex disease which could lead to other underlying diseases such as diabetes mellitus (DM), hypertension, and dyslipidemia. Urban population must manage their illness due to their occupation. Coaching support is an advanced method to help individuals manage their illnesses, especially chronic illness. Symptoms and complaints in early-stage renal disorders tend to be mild, making it difficult to diagnose only by clinical examination. Impaired kidney function can lead to progressive kidney damage. AIM: This study aimed was to analyze the effect of coaching support in maintaining kidney function in patients with CKD. METHODS: This research used quasi-experiment with pre-test and post-test with control group design. Respondents in this study were 40 CKD patients which were taken by consecutive sampling technique and divided into two groups, namely, control group and treatment group. Data were collected using blood urea nitrogen and creatinine values observation sheet. Coaching support was divided into four steps of therapy, identify the disturbance, identify based on experience, use a family support system, and evaluating the results. Data were analyzed using paired t-test and independent t-test with a significance of p < 0.05. RESULTS: This study found that there was a significant difference in kidney function between the control group and the treatment group (p = 0.000). Coaching support interventions were effective on kidney function in patients with CKD. The implementation of coaching support went well because respondents and families were proactive. CONCLUSION: Coaching support should be applied by nurses as daily activity management of CKD patients at early stage to inhibit the kidney function damage progression.
